Physics World September 7, 2018 Carbon fibres’ microstructural designs have been generated to realise a targeted mechanical property. An international team of researchers (Italy, Sweden, France) compared the microstructure and electrochemical performance for two types of commercial carbon fibre, middling mechanical properties and the hardest hitters in terms of structural strength. They found that the intermediate strength carbon fibres were much less organised but still had such high mechanical properties that even smaller crystals might still get good mechanical properties. According to the researchers exploiting the electrochemical properties of carbon fibres could drop device masses by as much as 50%… […]

Scientists design material that can store energy like an eagle’s grip
Science Daily August 9, 2018 Researchers in the UK have redesigned auxetic materials with smooth curves which distribute the forces and make repeated deformations possible. A major problem for materials exposed to harsh conditions, such as high temperature, is their expansion. The new material can be designed so its expansion properties continuously vary to match a gradient of temperature farther and closer to a heat source. It will be able to adjust itself naturally to repeated and severe changes. The work lays the basis for designs of lightweight 3D supports, which also fold in specific ways and store energy which […]
